Property, and subsequent Compound Machining is adapted to, it must well-designed formula for raw stock.
There are two types of method, hot-forming and UV curing moldings for micro-prism type reflecting material forming technique.UV solidification method be by
Traditional optics adds lustre to membrane process, has ready-made equipment and composition of raw materials, access threshold is lower, and moulding process is relatively simple
It is single；At type hardness tester height, good brightness, heatproof.But there are following wretched insufficiency, UV solidified resin is since material selection range is small, work
Skill formula is special, and price is 2-5 times of thermal resin, and hardly possible obtains index request required for reflective membrane；After resin UV solidification, point
Son is at cross-linked structure, it is difficult to use the compound hypoglyph of routine techniques, be unfavorable for following process and use, more seriously
Ultraviolet-curing resin itself is especially sensitive to ultraviolet light, and outdoor weathe resistance is very poor.
Heat pressing process is to form continuous roll film, raw material using the conventional heated rolling of thermoplastic resin material
It is easy to get, it is moderate, it is particularly easy to realize the diversification of material, Complex Function.And optical property is more excellent, and product quality is big
It is higher than UV solidification method greatly, is suitble to scale industrial production, the generally approval in market is obtained with the product that this technique produces.With heat
Plastic resin (such as polycarbonate) is shape layer, is current public affairs using mould pressing process production high-performance microprism reflecting film is squeezed out
The preferred approach recognized.Polycarbonate becomes micro-structured form layer with its excellent toughness, high transparency, high temperature resistant, easy processing
Preferred raw material；The reflective membrane production equipment use of hot pressing at present is primary hot-forming, is easy to make when resin film uneven heating
There is missing at local microprism array structure or filling is discontented, to influence the quality of reflective membrane, and due to microprism battle array
The area of array structure is small, directly tears off resin film and endless belt-shaped mold using external force, can pull micro- on resin film
Prism array structure.
